HEATER.

Application filed January 14, 1926. Serial No. 81,136i

This invention relates to heaters of im-' proved construction- It is an object of the invention to provide a device of the type stated which will embody a construct-ion by means" of which the response of the heater to the opening of drafts will be extremely rapid, and by means of which, when the fire is banked, the escape of coal gas will be prevented to a maximum extent.

A further object of this invent-ionis thatof furnishing a heater in which the parts accomplishing these results maybe renewed with facility, these parts being protected to a maximum extent against damage. An additional object is that of providing a heater which will efliciently perform the purposes for which it is intended, and which will also be economically and readily manufactured and easily assembled.

Other objects of. the invention W111 in part be obvious and will in part appear hereinafter.

The invention accordingly comprises the features of construction, combination of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the claims. For a fuller understanding of the nature and objects of the invention reference should be had to the following detailed description taken in connection with the. accompanying drawings, in which:

Figure 1 is a partly fragmentary sectional plan view of a tank heater embodying the improved construction of the present invention;and v Fig. 2 is a partly sectional side elevation thereof.

In these views the numeral 5 indicates the grate orbase section of the heater, upon which the firepot section 6 is mounted. A cored or water section 7 is supported by the section 6, and in turn supports an upper section 8. Mounted upon the upper edgeof the latter is a top or cover 9, from which a smokepipe collar 10 extends, this top being provided with a hinged firedoor 11.

It will be observed that all of these sections are preferably formed with flanges 12 quence, these sections are prevented from being relatively displaced.

The section 8, and, ifdesired, the section 6, are'lined with a layer of firebric'k or other suitable heat-retaining and insulating material 13'. By lining the lower section in this manner the firepot will be comparatively well insulated and will be heat-retentive. As a consequence, the side layer of fuel will not be readily chilled, resulting in a thick ness of dead fuel and accumulation of clinkers, etc., anda draft will be induced through the grate the heater.

Vith respect to the upper section 8 it will primaril be appreciated that this section is ordinari y above. the upper level of thefuel bed within the'heater', but will be very thoroughly heated during the operating thereof.

As a*consequence, when the fire is banked the lining of this section will begin to slowly giye off heat-,Which will result pot gases being generated. This heat will also cause flue to draw.

Thus, when the fire is banked, coal gas" 'Wlll not escape, in that, while this gas is ing thereof to a minimum it is preferred that certain of the sections carry inner flanges substantially in line with the inner faces of the linmgs 13. To this end, in the and body of" fuel within the fiue section to be preheated and causethe present exemplification, the top 9 is formed 'with a downwardly-extending flange 14-, and

the central section 7 is formed with an up weirdly-extending flange 15, while the base section is formed with a similarly-extending flange 16. These flanges are preferably complementary to the flanges 12 associated with the sections, and the linings 13 are preferably recessed adjacent their inner faces so that the parts may properly seat.

Thus, among others, the objects of this invention are accomplished, and since cer tain changes be made in the abeve can struction, and difl'erent embodiments of the lowing claims are intended to cover all of the generic and specific features of the invention hereln described and all statements of the scope of the nvention which as a V matter of language might be said to fall therebetween. I I Y Havlng descrlbcd my invention, what 1 claim as new and desire to secure by Letters 1 Patent is ,1. A heater, comprising a plurality of sections, a lining of fire-resistant and heat-retentive material positioned adjacent one of said sections, and a flange forming a part of an adjacent section andoverlapping certain portions of said lining.

'2. A heater, including a plurality ofsuperposed sections, a substantially horizontally-extending portion forming a part of one of said sections, and a lining of fireresistant and heat-retentiveniateria1 positioned adjacent another section and resting upon the horizontally-extending portion of said first-named section.

3. A heater, including a base, a firepot section mounted upon said base, a horizontally inwardly-extending portion forming a into said recess.

one of said sections and being formed with a recess, and a flange-portion forming a part of an ad acent heater'section and extending 5. A heater, including a plurality of superposed sections, a lining of fire-resistant.

heat-retentive material appliedto one of,- of said sections, and a substantially horizontal portion formed atthe upper end of a section below said first-named section, said lining resting upon said horizontal portion.

6. A heater, includinga plurality of Snperposed sections, a lining of fire-resistant, heat-retentive material applied to one of said sections, a substantially horizontal portion formed at the upper end of a section below saidfirst-named section, said lining resting upon said horizontal portion, a top applied to the upper edge of said first-nainedsection, and a downwardly-extending flange forming a part of said top and extending into a recess formed in the upper edge of, said lining. 1

In testimony whereof I. afiix my signature.
